Can anyone help. I recently upgraded to Windows 7 ultimate and since then when I put a DVD movie in the DVD drive I get no sound. All other sounds works on the system ie. music, games etc.

Since Windows won't natively play DVD movies, I assume you have some other program installed like PowerDVD. Since you upgraded, it's possible that this program, or the associated codec got messed up. Your best bet is to reinstall what ever DVD playing program you have installed.

Are you using different DVD player software since your upgrade? CD and DVD players should have an 'audio out' connection on the back of the unit. This allows a cable to connect from the player directly to the audio hardware. Most of the time that connection isn't needed as the software will take over the audio and control the output.

If you don't have that connected, it won't hurt to hook it up even if it turns out that's not the problem. There's probably two different 'audio out', one analog and one digital. You'd use whichever one your audio hardware takes.

Otherwise it's either a problem with your DVD software configuration or possibly a driver issue.

DVD drives don't require you connect an audio cable to them in order for you to hear sound. Recent ones may not even have the capabilty of connecting an audio connection to them. The sound is sent via the data cable from the drive to the computer.
The same applies to any optical drive made since the late 90's, if not earlier.

It's possible that if there's a problem with the data cable connection, you may get no sound.

It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try another data cable if in doubt.

E.g. there were two guys who posted here not long ago that had IDE hard drives and the hd activity led wasn't working for one drive. When they replaced the IDE data cable, the hd activity led worked fine for all the IDE hard drives.

Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)

The same thing applies for the SATA power connection.

"Since Windows won't natively play DVD movies, "

Vista and 7 do.

Are you playing a movie with DTS audio? Windows doesn't come with a DTS decoder, so if the DVD doesn't have a Dolby Digital backup track, you'll need AC3Filter. It's free.

If you can't get Media Player to use AC3Filter (it truly is a pain in the ass to change default DirectShow filters in Windows 7), try playing the DVD with MPC-HC.

MPC-HC is available here:

Turbocharged 939 | Dual-core Opteron 185 @ 3.2GHz | 2x 8800GTS in SLI | 4GB PC3200 @ CL2 | A8N32-SLI Deluxe |1TB | PCI-E X-Fi Titanium Pro | Swan D1080MKII + Dayton 10" 125w sub | W7 Ultimate
